- 説明
The inverter is a highly efficient three‑level power IGBT unit specifically designed for use in high‑power solar inverters and energy storage systems (ESS).
It is a key component for converting DC power from solar panels or battery banks into AC power suitable for powering industrial equipment or feeding into the power grid.
- High power output: delivers a rated output power of 476 kW, making it ideal for large‑scale industrial and grid‑connected solar power plants.
- Advanced topology: the three‑level circuit design ensures high output voltage quality with low harmonic content, reducing the load on grid equipment and improving overall system efficiency.
- Reliability: the use of in‑house IGBT modules manufactured by Proton‑Electrotex and an effective air cooling system ensure stable operation under harsh conditions as part of critical power equipment.
- Flexibility: operates with DC voltage up to 1 100 V, enabling integration into modern high‑voltage energy collection systems.
- Climate adaptation: the UHL4 climatic rating confirms its operability across a wide temperature range typical for most regions of Russia.
This solution, developed using an in‑house component base, demonstrates high competitiveness and complies with global quality standards for renewable energy equipment.
- 用途
The power unit is designed for use in solar power plant (SPP) inverters with a capacity of 750 kW and 1 500 kW, connected to a DC network with voltage up to 1 500 V. Typical applications include:
- Grid‑tied solar power plant inverters — converting energy from photovoltaic panels for supply to the electrical grid;
- Centralized solar power plants with capacity from 750 kW to several MW;
- Energy storage systems (ESS) — the three‑level NPC topology supports bidirectional power flow, enabling the use of the units in storage systems with grid regeneration;
- Hybrid solar power plants with battery storage — the three‑level design ensures integration of solar panels and batteries within a single converter;
- Industrial facilities with on‑site solar generation — factories, logistics centres, data centres.
Three‑level IGBT inverters of this class are used where highly efficient conversion of DC power (1 100–1 500 V) into grid‑quality AC power is required, with minimal losses, low harmonic content, and high reliability for 24/7 operation.
Parallel connection of the units allows building inverters of various capacities: a single unit delivers 476 kW; connecting several cells in parallel yields 750 kW; increasing the number of units enables capacities of 1 500 kW and above. This provides a modular design and system scalability without changing the base unit.
